Abstract: 1,040,303. Storing liquefied gases. PHILLIPS PETROLEUM CO. Feb. 4,1964 [Feb. 21,1963], No. 4647/64. Headings F4H and F4P. The vapour given off by a mixture of liquefied gases stored in tanks 7, 8 flows through a vapour withdrawal line 16, 18 and is compressed by compressors 44, condensed in heat exchangers 56, and returned through lines 23, 21 to the tanks 7, 8 where it is discharged through Venturi sleeves 20 disposed below the level of liquid therein, thereby cooling and agitating the stored liquid and reducing segration of more volatile liquid gas from less volatile liquid gas. The vapour withdrawn from the tanks 7, 8 prior to being admitted to the compressors 44 passes through a receiver tank 27 having a float valve 46 and also through a float valve 47 to prevent liquid entering the compressors. The condensed liquid returned to the tanks 7, 8 is collected in a valve chamber 62 having an outlet connected to the tanks and controlled by a valve 66 operated by a float 63. The tanks 7, 8 are shown installed in a ship 6 and are charged with the liquefied gases through lines 36, 34, 14 and 12, a pressure control 39, 41 being arranged to close a valve 38 in the line 34 in the event of excessive pressure occurring in the tanks. When unloading the tanks 7, 8, a pump 28 withdraws liquid gas from the receiver tank 27 and delivers through a valve 37 to the line 36 which is connected to an outlet line. When the level of liquid in the receiver tank 27 falls by an amount sufficient to influence a liquid level control 31, a valve 29 is opened and the receiver tank is replenished with liquid forced from the tanks 7, 8 by the pressure of gas therein. The pressure of the gas in the tanks 7, 8 may be increased by returning the gas withdrawn therefrom by the compressors through valves 53, 26 which bypass the heat exchangers 56.

Title: Process for the production of alkyl chlorides
IPC: C07C17/10
Filed: 1951-03-02
Abstract: Alkyl chlorides are prepared from saturated aliphatic hydrocarbons which are liquid under normal conditions by passing a mixture of gaseous chlorine and the liquid hydrocarbon downwardly through a vertical or inclined reaction tube provided with packing or passing the mixture uni-directionally through a horizontally disposed reaction tube provided with packing, the reaction tube being of glass or other transparent material and exposing the mixture to light in its passage through the tube, the liquid velocity being not less than 5 cms./sec. not taking into consideration the quantities of gas also flowing through the tube. The amount of chlorine used is preferably 0.1-0.3 gram atoms per mol. of hydrocarbon.  The reaction temperature is maintained at 70 DEG  C. or less.  Advantageously, any oxygen present in the initial hydrocarbon should be removed by blowing with nitrogen, HCl or other oxygen-free inert gases.  To prevent formation of dichlorides, hydrocarbon mixtures obtained, e.g., by catalytic hydrogenation of carbon monoxide should be freed of olefines and alcohols by dehydration over alumina followed by catalytic hydrogenation or preferably by separating the hydrocarbons into fractions containing the same number of carbon atoms and purifying as described hereinafter.  The reaction tube is preferably illuminated along its length in a manner whereby the intensity of the light increases in the direction of fluid flow.  In examples: (1) a C10 carbon monoxide hydrogenation fraction is freed of olefines and alcohols by treatment with HCl in presence of aqueous zinc chloride and distillation to remove alkyl chlorides so produced; the purified hydrocarbon fraction is blown with nitrogen and then fed with chlorine down the annular space of the reactor formed by two concentric glass tubes inclined at 5 degrees to the horizontal, the outer tube being water-jacketted and externally illuminated and the annular space being filled with glass beads; the resulting product is distilled to separate the alkyl chlorides from polychlorides and unchanged hydrocarbon.  (2) A heavy naphtha fraction consisting of 60 per cent. C10 aliphatic hydrocarbons and 40 per cent. naphthenes is blown with hydrogen chloride and then chlorinated as in (1) using, however, a vertical reaction tube.

Abstract: 143,963. Wellington, J. M., and Mackenzie, D. G. March 1, 1919. Grab-buckets.-Relates to single-chain grabs of the kind in which the lower shaft approaches the grab-head during closing and the upper and lower shafts are automatically maintained at their full distance apart for lowering after discharging, and consists chiefly in replacing the usual ball release by a pin-and-slot linkage device which controls the angular position of the suspending-hook. The buckets 1 are suspended from the upper shaft 3 by the usual links 4 and are also provided with short links 10 connected by a pin 11. The suspending-hook 8 has at one side a depending arm 12 carrying the upper sheave 6, and at the other side a second depending arm 13 having a curved slotted extension 14 engaging the pin 11. In operation, when lifting with the buckets closed, the suspending-hook is so inclined that it engages with the opening-ring 9. The chain is then slackened to allow the buckets to open and discharge, and the pin 11 travels up the slot 14 and engages in the terminal recess 14<11>, so holding the hook vertical and disengaged. After lowering the bucket to the ground, the pin is released by slackening the chain, so that on winding in the rope, the pin travels down the slot to the original position. In a modification, a rocking lever 15, Fig. 6, is mounted on the pin, the lever having a notched end adapted to engage a locking-stud 16 on the suspending-hook, and a looped end 15<11> through which the chain passes.
